NOVELTY - A manganese titanate/graphene composite material preparing method involves mixing manganese dioxide and graphite oxide with n-butyl titanate or titanium tetrachloride to obtain a mixture, and subjecting the mixture to hydrolysis reaction at 80-200 degrees C followed by washing with water, filtering, removing impurity and drying to obtain a manganese titanate/graphene composite material. USE - Method for preparing a manganese titanate/graphene composite material that is utilized for a capacitor. ADVANTAGE - The method enables preparing the manganese titanate/graphene composite material with excellent property in a simple manner.
